It depends on the year make and model of your vehicle where the brake controller fuse may be located. If you have a factory towing package the fuse is sometimes labeled "trailer tow electric brake". You can check the fuse visually to see if it's been blown or remove the fuse and replace it with a new one of the same amperage to see if it fixes your issue.

If you do not have a towing package and the brake controller is an aftermarket installation, you may not have a fuse. The brake controller is wired via a circuit breaker to the battery.
